Deleting Partition (no installation cd)

I bought my B&W g3 rev2 off of eBay a few months ago. When it came, it included the default 9gig HD, but it was partitioned into two different drives.

I recently purchased an 80gig WD drive, and I was hoping to get rid of the 2nd partiton on the original drive. I've done a lot of searching, and everyone always says to put in the OS cd and do it that way, but my mac didn't come with an OSX installation cd (I recently purchased a Panther upgrade cd, but I don't think that will do me much good. It's set to arrive on Tuesday.)

Does anyone have any ideas? When I go into the Disk Utility, over on the Partition tab, both of them are locked, so I can't delete it that way. I am on as the single user with admin priviledges.

the panther cd you ordered is exactly what you need. apple doesn't sell "upgrade" discs for their OS; it is the full OS--so you'll be able to format the drive that way. just wait til tuesday when you get panther.
